R44 Catless Downpipe For BMW S58 G8X M3 / M4
We are proud to introduce our new R44 S58 Catless Downpipe for 2021 G80/G82 M3 & M4. Reduce backpressure by eliminating the restrictive catalytic converter in the factory downpipe which results in a faster spool, an increase in power and a more aggressive exhaust note. Handcrafted from stainless steel and CNC precision-machined flanges constructed from billet 304-grade stainless steel.
- Made from hand-crafted, tig welded 304-grade stainless steel.
- Smooth radius bends to decrease turbulence and increase flow.
- Lighter weight than the factory system
- Quicker turbo spool
- Increased low end and mid-range power
- BMW M3 (G80) (2021+) 3 Series S58
- BMW M4 (G82) (2021+) 4 Series S58
